LOTHROP A. HAYDEN, OF SOUTH CARVER, MASSACHUSETTS.

FEED ATTACHMENT FOR CRANBERRY-SEPARATOFIS.

Specification of Letters Patent.

Patented Nov. 28, 1905.

A lication filed October 1, 1903. Renewed September 15, 1905. Serial No. 278,635.

To all whom it may concern:

Be it known that I, LOTHROP A. HAYDEN, a citizen of the United States, residing in South Carver, in the county of Plymouth and State of Massachusetts. have invented new and useful Improvements in Feed Attachments for Cranberry-Separators, of which the following is a specification.

This invention relates to feed attachments for cranberry-separators in the broad sense of the term, in which are included winnowers and cullers; and it relates particularly to that class of separators which includes the invention described and illustrated in Letters Patent of the United States granted to me November 13, 1900, and numbered 661,801, to which reference is made.

This invention relates specifically to the construction of the feed portion or feed attachment for cranberry-separators whereby the berries are fed into the machine, the particular object of this invention being to allow berries of different sizes to be introduced individually into the machine, said berries, as well as the stones, &c., passing under springs which yield individually to the berries and stones without causing the entire opening in the feed to be enlarged by the passage of a large stone.

The nature of the invention is fully described below and illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of my improved feed making a part of a cranberry-separator, a sufficient portion of which is shown to illustrate the operation of the invention. Fig. 2 is a rear elevation of the feed removed. Fig. 3 is an enlarged detail of a portion of the under side. Fig. 4 is a section taken on line 4:, Fig. 3.

Similar letters of reference indicate corresponding parts.

(t represents one of the uprights making a part of the frame of a cranberry-separator. Z) represents the throat or well, provided with bounce-boards 0, dividing-boards cl, and inclined shelves 6, and f represents a flue extending from a blower g to the path of the berries as they drop from the feed, all as illustrated in the Letters Patent above referred to and not new in this invention.

' it represents the opposite side walls of the feed or hopper, whose frame rests on the top of the main portion of the separator.

n is a bottom inclined downward toward the roll p, sustained by the frame 70 and driven from the main shaft. Opposite this inclined floor n is an inclined end board .9, to the under side of which is pivotally secured at one end a lever m, to which is pivotally secured the upper end of a bar 0, which supports the cross piece or head 1, adapted to slide in ways in. To the under side of this cross-piece are secured at 2." any desired numbersay twelve of springs 2/, whose lower ends are secured at t to the under side of blocks or small platforms a, each of which supports at its lower end a small freely-rotating roll a). The rolls Q) are as close as possible to their supports without interfering with their rotation, and the roll 12 is similarly situated with relation to the inclined bottom at. As the berries are poured into the feed or hopper they roll down the surfaces of the parts a and s and crowd between the roll 0 and the small rolls '2), the springs 25, which are independent of each other, yielding each sufficiently to allow theparticular berries with which they come in contact to drop between the small rolls 2; and large roll 9 into the machinethat is to say, the springs t yield and allow their platforms at and rolls 0) to move back or outward a short distance for a small berry or a greater distance for a large berry. Thus berries of all sizes are accommodated and fed into the machine. Moreover, when a large stone passes through the feed a single spring only is obliged to yield, or perhaps two springs; but the rest of the opening is not affected.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

In a feed attachment for cranberry-separators, the inclined floor n,- the oppositely-inclined boards; the cross-bar 1* supported by said board; a series of springs extending downward from said cross-bar; aseries of platforms or blocks a each of which is supported yieldingly by one of said springs; a roll supported by each platform near its lower edge; and a roll supported by the frame near the lower edge of said floor and opposite the row of rolls supported by the platforms, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LOTHROP A. HAYDEN.
